10 Rockwell Automation Publication 1769-UM012B-EN-P - January 2014
Chapter 1 Compact I/O ASCII Module
Environment and Enclosure
WARNING: This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as defined in
IEC publication 60664-1), at altitudes up to 2000 meters (6562 ft) without
derating.
This equipment is considered Group 1, Class A industrial equipment according to
IEC/CISPR Publication 11. Without appropriate precautions, there may be
potential difficulties ensuring electromagnetic compatibility in other
environments due to conducted as well as radiated disturbance.
This equipment is supplied as open-type equipment. It must be mounted within
an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The enclosure must have suitable
flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-
metallic. The interior of the enclosure must be accessible only by the use of a
tool. Subsequent sections of this publication may contain additional information
regarding specific enclosure type ratings that are required to comply with certain
product safety certifications. In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley
publication 1770-4.1
, for additional installation requirements
• NEMA Standards publication 250 and IEC publication 60529, as applicable,
for explanations of the degrees of protection provided by different types of
enclosure
